The only danger is from things like DOS based upon ping/ping floods. There is no bullseye on your machine because it responds to pings. I suppose that there might be some kind of stealth program to hide what your machine OS is but chances are that an up to date nmap would likely fingerprint it anyway unless you really work it to make it appear like it were a Windows machine. Anyway, to answer the OP... You can check if system is alive and responding via ping. If you shut that off, you wouldn't get a response so you would have to resort to other methods to test for the presence. The posit that permitting pings represents a security threat is highly subjective and I surely haven't see anything in that answer or in any relatively current kernel that makes me worry about it.
